Really this is the reason why England should make changes to the batting order not sure what people expected differently from Hales, Vince or ballance.
Making a change is a negative move it can be a postive direction.
Really pakistan have made good changes in this series.
New opener scores runs, Sohail khan takes wickets and then Wahab bowls a brilliant spell when he comes back in the side.
Sometimes players needs a break, a kick in the backside or they just been found out mentally and a new player could score runs while the opposition don't know much about them.
At the moment pakistan know how to get Hales, Ballance and Vince out.
